The short-time delayed characteristic provides selectivity with downstream RCCBs — it holds during transient earth faults (e.g., from motor starts or capacitor switching) so only the faulted sub-circuit trips, not the main board. Rated current holds at 63 A from 40 °C through 60 °C (–), then derates to 57.35 A at 65 °C and 48.8 A at 70 °C (–). That's a clean thermal curve — no derating needed in a standard 40 °C panel, but if the board sits near a heat source or in a hot environment, account for the drop above 60 °C. Depth is 70 mm — that's the body depth; the terminals accept top or bottom feed, so plan your busbar routing accordingly. IP20 rating applies when installed in a distribution board with conductors connected — it's not a standalone outdoor device.","metaTitle":"Siemens 5SV4346-0LA01 SENTRON RCCB, 63A 30mA 4P Type AC","metaDescription":"Siemens SENTRON 5SV4346-0LA01 RCCB, 4-pole, 63A, 30mA Type AC residual current, short-time delayed, 10kA SCCR, DIN rail mount.
